Every hour as its own page

GMT to SAST — questions

What time is it in SAST when it is GMT now?
SAST is currently 01:28 on Thursday, 13 August 2026 (SAST, UTC+02:00), while GMT is 23:28 (UTC+00:00). That is 2 hours ahead of the source clock right now.
How many hours ahead is SAST of GMT?
2 hours at this moment. The gap is not constant across the year: Greenwich Mean Time and South Africa Standard Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is SAST on daylight saving time right now?
No. Africa/Johannesburg is on SAST (UTC+02:00) at the moment.
Does SAST observe daylight saving time?
No. Africa/Johannesburg stays on UTC+02:00 all year, so the difference from GMT only moves when GMT itself changes.
What is the best time to schedule a call between GMT and SAST?
There are 7 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–16:00 GMT, which is 11:00–18:00 SAST. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for SAST in code?
Use Africa/Johannesburg. Abbreviations like SAST are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+02:00 instead will be wrong the moment the rules change.
